Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186254, here are decompositions:

7 + 186247 = 186254
43 + 186211 = 186254
67 + 186187 = 186254
97 + 186157 = 186254
151 + 186103 = 186254
157 + 186097 = 186254
241 + 186013 = 186254
283 + 185971 = 186254

Showing the first eight; more decompositions exist.
